Tritech Micron Gemini
The Micron Gemini is the latest addition to Tritech’s Micron and Gemini product families and offers powerful, real-time sonar imaging in the body of a Gemini 720im. With greatly improved image quality, a 90 horizontal field of view and 50m range, the Micron Gemini offers cost effective obstacle avoidance and navigation for small ROVs and AUVs.
Description
With Tritech’s advanced processing electronics, the Micron Gemini operates at 720kHz, to produce images of outstanding clarity. The system benefits from 128 beams and an effective angular resolution of 0.7.
The Micron Gemini comes with a built in pressure sensor which provides a depth reading, as well as optional AHRS.
The Micron Gemini has incredibly compact dimensions and is ideally suited for micro ROV/AUV applications when real-time, video-like imagery is required, and where space is restricted or weight is critical, such as diver helmet and pole mounted applications for Search and Recovery (SAR) operations.
